PUMP.

SPECIFICATION Vforming part of `Letters Patent No. 265,191, dated September 26, 1882.

Application tiled June 20, 1882. (No model.)

1b all whom it may concern Be it known that I, JOHN VALGHER, ofthe city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Pumps, ot' which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part ot this speciiication, and in which- Figure 1 is a front view. Fig. 2 is a back view. Fig. 3 is a section on line 3 3, Fig. 4. Fig. 4 is a section on line 4 4, Fig. 3. Fig. 5 is a section' on line 5 5, Fig. 3. Fig. 6 is an enlarged detail perspective view illustrating the manner ot' securing the Lipper valves in place, and/Fig. 7 is a similar view illustrating the manner ot' securing the lower valves in place.

My invention relates to a pump having an oscillating` piston5and my invention consists in the construction of the pump, as hereinafter described.

The body ot thepump consists of sides A A, cast in one piece, a removable back, B, connected to the sides by suitable means, removable front O, connected to tbe sides, and removable top D, connected to the sides and to the front and back.

E is an inside shell, cast in one piece with the sides A.

F represents the water-inlet.

\ Gr is the oscillating piston, provided with a suitable packing, El, and workingin a cylinder or chamber, I. The shaft J ofthe piston basa bearing at one end in a centered screwplug, K, titting in an opening ot' the back, B, and provided with a suitable gasket, L. The other end of the shaft is journaled in a plug, M, screwing into the front,:C, and provided with a suitable packing, N.

O is a crank on the shaft for operating the piston. A packing,`I, should be between the shaft ot' the piston and the shell E.

Q Q' are lower water-openings in the shell, and they are provided with Hap-valves R R'. These valves are secured, as shown in Fig. 7, to removable plates S S, which iit in grooves of the shell. Thus the valves can be easily removed for repairs, Src., by taking off the back or front.

T T! are upper Waterbpenings iu the shell,

and they are provided with iapvalves U U',

held in place by a removable plate, V, which has legs V'. The plate Vis concave on its upper surface', so as to fit the convex surface ot' the shell below the piston. The legs of the plate are notched to rrceive a rib oit' the shell. (See Fig. 6.) The upper portion of the shell forms a water-chamber, W, above the valves U, which communicates by means of an opening, X, and channel Y with an ordinary waterchamber, Z.

W' is the water-outlet communicating with the chamber W, and which would be provided with a suitable spout.

The shell E has openings, closed by screwplugs E' when the pump is in use, directly over the openings T T' Q Q', for the insertion of an iustrumentstem when the top D is removed for tting up the val\'e-seats.r

The Voperation of the pump is as follows: The piston, being moved in the direction shown by the non-feathered arrow, forces the water before it, as shown by the arrows, down the channel between the shell and that side ofthe case, and up through the apvalve opening T into the chamber W, from where it flows out ofthe pump. While the piston is being moved in this direction it draws water up through the valve-opening Q, through the channel between the shell and that side ot the pump into the cylinder or chamber I. Then when the piston is moved to theoiller side it t'orees and draws water in the other direetionsand so on.

I claim- 1. The combination of body A B O lD, and piston G on shaft J with crank-,shell E and valves` R R' U U', all constructed substantially as` shown and described.

2. The combination of body A B O D, having channel Y, openings X Q Q', and shell E, havingopenings T T', and plugs E', the chamber Z, shaft J, piston G, centered plug,l K, journal-plug M, and valves R R' and U U', as set forth. t
